Waste of polymer products, especially plastics, in nature has become a problem that caught the awareness of the general public during the last decade. The macro- and micro polymers in nature will be broken down by naturally occurring events such as mechanical wear and ultra-violet (UV) radiation which will result in the generation of polymeric particles in the nano-size range. We have recently sho

Vulnerability maps of groundwater provide an efficient means of identifying environmental trends and prioritizing regions for prevention plans. The GIS-based DRASTIC method, however, does not consider the impact of contamination, so there is a need to modify it according to the specifics of the region and its contamination load. The aim of this study is to investigate a suitable DRASTIC modificati

Berättelsen om hur det moderna Sverige växte fram har länge varit förenklad. Övergången från ett förmodernt, patriarkalt samhälle till ett modernt och demokratiskt beskrivs gärna som medelklassens och centralmaktens förtjänst. Men något som ofta har utelämnats är de religiösa väckelsernas bidrag särskilt de extatiska och mer provocerande rörelserna.I denna antologi ger fjorton forskare från olika

The human brain can be described as a complex network of functional connections between distinct regions, referred to as the brain functional network. Recent studies show that the functional network is a dynamic process and its community structure evolves with time during continuous task performance. Consequently, it is important for the understanding of the human brain to develop dynamic communit

Purpose: There is limited research on the behavior of different categories of space tourists as identified by different types of space tourism. To address this deficiency, the purpose of this study is to examine what factors make consumers participate in orbital and/or suborbital space tourism, along with three dimensions of motivation, constraint and artificial intelligence. To achieve this study

In this paper, we study the trade-off between complexity and performance in massive MIMO systems with neural-network based digital pre-distortion (NN-DPD) blocks at the base station. In particular, we consider a multi-user massive MIMO system with per-antenna NN-DPDs, each with an adjustable NN architecture in terms of the size and the number of NN hidden layers. We first analyze the system perfor

BACKGROUND: Comprehensive insight in the longitudinal development of health-related quality of life (HRQOL) after childhood cancer diagnosis could improve quality of care. Thus, we aimed to study the course and biopsychosocial determinants of HRQOL in a unique national cohort of children with cancer.METHODS: HRQOL of 2154 children with cancer was longitudinally reported (median: 3 reports) between

We investigate self-heating in vertical, gate-all-around III-V InAs/InGaAs nanowire MOSFETs using pulsed IV measurements at various temperatures. Low temperature measurements reveal a negative output conductance indicating self-heating in the transistor. Under pulsed measurements, an increase in drain current (15%) and transconductance (30%) are observed at room temperature, with values influenced

In this article I investigate the spatial development of Swedish district courthouses and their different room types from 1970 to 2020, with attention to the specificities and commonalities with other building types. How have spatial form and use travelled between building types during this period, and how has this contributed to the recent, quite radical developments and transformation of the cou

A conceptual design of a year 2035 turbofan is developed and integrated onto a year 2035 aircraft model. The mission performance is evaluated for CO2, noise and NOx and is compared with a notional XWB/A350-model. An OGV heat exchanger is then studied rejecting heat from an electric generator, and its top-level performance is evaluated. The fan, the booster and the low-pressure turbine of the propu

Western missionaries became important eyewitnesses of the 1915 Armenian genocide, and many reported on the events. This article analyses witness reporting from a biographical and gendered perspective, taking into account the significance of studying local activism and transnational networks in a humanitarian setting. Taking the witness accounts of the Swedish missionary Alma Johansson as an exampl
